The operator, running with cluster-wide Secrets RBAC, reads the victim-namespace KafkaUser Secret (SASL credentials or TLS private keys) and writes the plaintext material into a Secret in the attacker's namespace. No same-namespace check or allowlist exists anywhere in the code path.","cvssScore":7.7,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","cwes":["CWE-441"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-105311","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2510875","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
